Two-Generator Discrete and Faithful Subgroups of Tree Automorphisms

Yukun Du

We present a partial classification of two-generator discrete and faithful subgroups of the trivalent tree automorphism group, specifically for cases where the generators satisfy a…

Geometry of Selberg's bisectors in the symmetric space $S L (n, R) / S O (n, R)$

Yukun Du

We study some properties of a family of symmetric spaces, namely $S L (n, R) / S O (n, R) =: P (n)$ , where we replace the Riemannian metric on $P (n)$ wit…
